Hi all, I have now tried to install Lustre following the report https://mail.clusterfs.com/pipermail/lustre-discuss/2006-October/002311.html It all works reasonably well until I try to access the Lustre FS after I mounted it on a client. A simple "ls" may hang immediately, it may also work, as well as creation of files, reading, moving and deletion, but at some point a command will hang and the kern.log says:

Anybody seen this bug before? The failed command, of course, cannot be killed. The Lustre FS may be unmounted with "umount -lf" and mounted again, usable until the next command hit this bug. Btw, the code to set up the Debian package that is contained in pkg-lustre on svn.debian.org still uses the Lustre 1.5.97 sources. However, the code for 1.6.0.1 has already been uploaded to that repository - any plans to follow up with the Debian code soon?
